WIRELESS COMMUNICATION CORRECTNESS DETERMINATION SYSTEM
PROBLEM TO BE SOLVED: To provide a wireless communication correctness determination system capable of discouraging illegal establishment of wireless communication that uses a relay.SOLUTION: Communication is made between a vehicle 1 and an electronic key 2 with UHF electric wave of the same frequency band. The electronic key 2 calculates a reception signal intensity of the electric wave from the vehicle 1, and the reception signal intensity is transmitted to the vehicle 1 as a reception signal intensity information 30. At the vehicle 1, a difference between the reception signal intensity information 30 being notified and a reception signal intensity of the electric wave containing the reception signal intensity information 30 is calculated, and by confirming whether or not the difference is within a reference range, communication correctness of smart communication is determined.SELECTED DRAWING: Figure 1
【課題】中継器を使用した無線通信の不正成立を生じ難くすることができる無線通信正否判定システムを提供すること。【解決手段】車両１と電子キー２との間を同一周波数帯のＵＨＦ電波で通信し、電子キー２では車両１からの電波の受信信号強度を算出して、その受信信号強度を受信信号強度情報３０として車両１に送信する。車両１では、通知された受信信号強度情報３０と受信信号強度情報３０が乗った電波の受信信号強度の差分を算出して、この差分が基準範囲にあるか否かを確認することにより、スマート通信の通信正否を判定する。【選択図】図１
